Mora water solutions are dedicated to providing long term, large scale, fresh drinking water to where it is needed most, but people are dying today from dehydration and from disease through having no choice but to drink contaminated water.
In this series of articles we will review some of the solutions and technologies that are in place now to stop this happening:
Water Purification Ceramic Disc
PureMadi, a nonprofit University of Virginia organization, have introduced a simple ceramic water purification Called MadiDrop.
The tablet – developed and extensively tested at U.Va. is a small ceramic disk impregnated with silver or copper nanoparticles. It can repeatedly disinfect water for up to six months simply by resting in a vessel where water is poured. It is being developed for use in communities in South Africa that have little or no access to clean water.
The filters produced at the factory are made of a ceramic design refined and extensively tested at U.Va. The filters are made of local clay, sawdust and water. Those materials are mixed and pressed into a mold. The result is a flowerpot-shaped filter, which is then fired in a kiln. The firing burns off the sawdust, leaving a ceramic with very fine pores. The filter is then painted with a thin solution of silver or copper nanoparticles that serve as a highly effective disinfectant for waterborne pathogens, the type of which can cause severe diarrhea, vomiting and dehydration.
PureMadi established a water filter factory in Limpopo province, South Africa last year, employing local workers who have already produced several hundred alternative flowerpot-like water filters.
This means that it is likely to attract support from other companies eager to demonstrate their commitment to sustainability and regional development.
